Multiple vulnerabilities has been discovered and corrected in
java-1.7.0-openjdk:

An input validation flaw was discovered in the font layout engine in
the 2D component. A specially crafted font file could trigger Java
Virtual Machine memory corruption when processed. An untrusted Java
application or applet could possibly use this flaw to bypass Java
sandbox restrictions (CVE-2013-5907).

Multiple improper permission check issues were discovered in the
CORBA, JNDI, and Libraries components in OpenJDK. An untrusted Java
application or applet could use these flaws to bypass Java sandbox
restrictions (CVE-2014-0428, CVE-2014-0422, CVE-2013-5893).

It was discovered that the Beans component did not restrict processing
of XML external entities. This flaw could cause a Java application
using Beans to leak sensitive information, or affect application
availability (CVE-2014-0423).

It was discovered that the JSSE component could leak timing information
during the TLS/SSL handshake. This could possibly lead to disclosure
of information about the used encryption keys (CVE-2014-0411).

The updated packages provides a solution for these security issues.
